Nah, I got a arcade stick (although I recently lent it to a friend). It is just with Soul Calibur, I don't have the patience to learn all of the moves with all the characters, since I want to play as all of them. With Street Fighter, 9/10th the roster bores me, so it is easier to learn everything I want to learn!
Yeah, I love all the Marvel stuff in UMvC3, but a lot of the Capcom stuff is "meah," specifically the roster. Although I love the Phoenix Wright addition, even if he sucks!
YK. Rool is the most requested 1st/2nd party character not in smash yet. It's not hard to see why. I love the guy. I would love to see him in it, especially with that DKC2 gun. I would spam that thing all day every day.
Other characters I really want are all the Brawl characters to return (maybe minus Pit, since Brawl Pit mains for the most part are the definition of hell), Ridley (aka the God I worship), Mega Man (I'm sure you could have guessed that),
Dixie Kong (dat hair), Mewtwo (the one character everyone wants back), Roy (with a new moveset), Paper Mario (2Dx2 perhaps), and Geno (even if he has a very minute shot).
It seems kinda weird that most of the "major Nintendo characters" are already playable in smash. All that's really left are a few new Pokémon (as always), K. Rool, Mewtwo, and maybe Dixie Kong, Paper Mario, and Ridley. It's kinda weird how Brawl added in almost all of the big names left.
